SCREEN CONSTRUCTION.

Application filed March 30, 1928. Serial No. 265,845.

The invention relates to improvements in screen construction. The object is to provide improved means for forming a screen, especially for windows of any dimension. and means for mounting the same in slidable relationship with the window frame.

The invention comprises frame elements which are adapted to be cut to size, and means whereby said elements are locked together and in engagement with the wire mesh for which it forms the frame.

The invention also comprises improvements in corner elements adapted to be associated with the top and side frame elements. The invention also comprises means for supporting the completed screen. in slidahle relation with the window frame.

The invention is especially adapted to sheet metal construction; the metal being preferably non-rustable or non-corrosive, such for example as copper, brass, zinc, galvanized iron or the like.

Referring to the drawings which illustrate, merely by way of example, a suitable embodiment of the invention;

Fig. 1 is a front elevation of a portion of the screen and frame, with a slideway or channel formation for supporting same indicated in broken lines.

Fig. 2 is a section on line 2, 2 of Fig. 1 on an enlarged scale, showing the channel formation in full lines.

Fig. 3 is a plan of a portion of the blank from which the side elements are formed.

Fig. 4 is a perspective View of the same bent into shape for engaging the wire mesh, also shown.

Fig. 4 is a similar view of a modification.

Fig. 5 is a plan of a blank for forming the corner brace of the frame.

Fig. 6 is a perspective view of the same bent into shape for engaging the adjacent ends of the side elements and also the mesh.

Fig. 7 is a perspective view of a channel formation for slidably supporting the screen. Fig. 8 is a similar view of a modification.

Similar numerals refer to similar parts throughout the several views.

The fiat blanks or strips of sheet metal 15 are formed with tongue formations 16 struck out near one side margin. Slots 1'? are formed on the strip near the opposite margin so as to register with the tongues. The blank 15 is then bent at approximately its longitudinal middle along the dotted line 18, thus forming a folded side strip 19. These strips 19 may be furnished to the customer in any desired or standard lengths, to be cut by the user in lengths corresponding to the dimensions of the window opening.

W hen the margin of the wire mesh 20 is inserted into the folded strip 19, as shown in Fig. 4, the tongues 16 are passed through the mesh and through'the slots 17 and bent over as shown, thus securing the side strip firmly to the mesh.

here it is desired to use exceedingly thin sheet metal in making ments, the strips may be corrugated as shown in Fig. 4 which add substantially to the rigidity of the strip.

This Fig. 4- also shows a tongue or projection 16 extending from the end of one fold and bent around the adjacent end margin of the other fold.

When the four side strips are secured in place, corner braces are then secured around the adjacent ends of the side strips.

The corner braces are formed of a sheet metal blank 21, as shown in Fig. 5, adapted to be folded together along the dotted line 22. This blank 21 is also provided with tongues 24 and cooperating slots 25 so that when the said corner brace 23 is slipped over the adjacent ends of the strips 19, the tongues 24 are forced through the mesh and through the slots 25 and bent over as shown in Fig. 1. A projecting part 26 is also provided at one margin of the blank 21, extending about onehalf of the longitudinal extension of the blank, to be folded over to embrace the balance of the adjacent margin of the blank, as shown in Figs. 1 and 6, thus locking the parts securely together.

Two forms of channel supports are shown for slidably supporting the frame of the screen.

In Fig. 7 the channel structure 27 is provided with four folds as shown. The outer layers or extensions 28 are adapted to embrace a stationary bead formation, such as 29, on

the window frame. This channel structure may be additionally secured in place by nails or brads 30. The middle part of the structure forms the channelor way 31 for the side elements of the frame.

In Fig. 8 the channel formation 32 is provided with the flanges 33 for securing by similar nails or brads 31 to a flat surface of the frame.

tie side frame ele- All of these metal strips are preferably of very thin sheet metal, such for example as brass or copper, which are easily cut into proper lengths to form the screens and channel pieces of required dimensions. The side strips and channel formations may be provided as above stated in stock lengths, in bent or partially folded position. The side elements and channel elements may be cut to required lengths before assembling. l i hen the mesh is inserted between the folds, the folds are forced together and the tongues or projectiens of one told are bent into locking engagement with the other fold. No tools are required in this assembly beyond shears or hack saw and a hammer.

l hat I claim is 1. In a screen construction, the combination with a wire mesh sheet, a channel trame element formed of strip of sheet metal, having a single told which is along its middle longitudinal line, said frame element having a plurality of tongues struck out of the body of one ply of the strip within its margin and registering recesses in the other ply, said tongues adapted to project through the screen and the registering recesses and to be bent over and locked with the recessed ply.

2. In a screen construction, tie combination with a wire mesh sheet, a channel frame element formed of a strip of sheet metal, having a single told which is along its middle longitudinal line, said frame element having a plurality of tongues struck out 01 the body of one ply of the strip within its margin and registering recesses in the other ply, said tongues adapted to project through the screen and the registering recesses and to be bent over and locked with the recessed ply, one pl y also having a tongue projecting from one end margin for locking with the end margin of the other ply.

3. In a screen construction, the combination with a wire mesh sheet, a channel tramc element formed of a strip of sheet metal haw ing a single iold, which is along itsnliddle longitudinal line, said frame element having a plurality of tongues struck out of the body of one ply or the strip, within its margin, and 1 tering recesses in the other ply. said ton ues adapted to project through the screen and the registering recesses and to be bent orer and locked with the recessed ply, each ply having parallel longitudinal beads one near the line of fold and one adjacent the outer margin of the ply.

In a screen construction, the combination with a wire mesh sheet, channel iranie elemen formed of strips of sheet metal, each hating a single told, which is alongits middle longitudinal line, each channel element having a plurality of tongues struck out ol' tl e body ot one ply ot the strip, within. its margin. and registering recesses in the other ply aid tongues adapted to project through "con and the registering recesses and to 0V and locked with the recessed pl), and corner braces for engaging adjacent ends ot the channel elements, comprising sheet metal formations bent into a two-ply formation ith tongues struck from within the bodyof one ply and cooperating registering recesses formed in the bodv of the other ply.
